This is using Logos 7.5 (7.5.0031) on Windows 10
If I insert a Bible reference into a Sermon document it seems fine on Windows but when it syncs to the mobile apps (either on iOS or Android) the text is not completely enclosed in the surrounding box as shown below

I'm posting here - as opposed to the mobile reader apps forum - as this only seems to be an issue with newly created references. References in older sermon documents still appear correctly so it looks as though this is due to a recent change in the desktop software.
